Optimization and Extrapolation to Pilot Scale of Essential Oil Extraction from Pelargonium Graveolens, by Steam Distillation
Author(s): Rabesiaka JR, Pierre HR and Razanamparany BRabesiaka JR, Pierre HR and Razanamparany B
Essential oil extraction of Pelargonium graveolens that uses the extraction by steam distillation principle was studied at two scales: Laboratory scale and pilot scale. Firstly, a simple mathematical model was considered in order to optimize the effect of parameters that can influence the yield at the initial stage. This mathematical model is in the form of first polynomial degree with 3 variables for which the coefficient evaluation is done by multilinear regression. In order to reduce errors between calculated and experimental values, an optimal design was realized then followed by corresponding experiments to the plan. The complete factorial design 23 was used. The obtained model is as shown: Y = 2,156 - 0,183X1+0,060X2 - 0,038X3 - 0,012X1X2 +0,035X1X3 +0,037X2X3 .. View More»
